The zany, politically incorrect Williard brothers are back, and this time they're shooting for Mars, trying to spend the billions of dollars inherited from the Mafia Godfather. But there's a financially and politically powerful organization that's been seriously hampering manned space flight for more than two generations, backed by shadowy beings who may not have originated on Earth at all. So far they've kept manned space flight from progressing very fast or far, but they've never confronted the Williard brothers either. Along with their girlfriends, the Williards intend to go to Mars or die trying -- a distinct possibility!
